=== About the outline of the game ===
An outline of the game provided by the game system 1 will be described.
In the game system 1 of this embodiment, a battle game performed using a game medium can be provided to a player (user). Below, the baseball card game performed using the game card as an example of a game medium is demonstrated. Since this game card is a game card as digital content, it becomes a virtual card used in a virtual space on the game.

<Baseball card game>
The game system 1 according to this embodiment plays a baseball game between a group of game cards organized by a player and another player or computer game card group that is an opponent, and wins a tournament held in the game. Provide a baseball game for the purpose of playing.

  In the baseball card game of the present embodiment, first, a team for a player to play a game is formed. A team for playing a game is composed of nine players (that is, nine game cards). The player selects nine game cards from among a plurality of game cards owned by the player and forms a game card group corresponding to a “team”. Hereinafter, this game card group is also called a deck. Note that the number of game cards constituting the deck is not necessarily nine, and a substitute player may be included in the deck.

  Each game card has an attribute (position in baseball). For example, when “Pitcher” is set in the deck, one game card having the “Pitcher” attribute is selected and set from among a plurality of game cards owned by the player. Similarly, when “outfielder” is set in the deck, three game cards having the “outfielder” attribute are selected and set from among a plurality of game cards owned by the player.

  Once the deck (team) is organized, you can play matches with other players and computer decks (teams) using the deck. The winning or losing of the game is determined based on the parameters set for each game card constituting the deck. For example, there is a method of determining the victory or defeat by comparing the total attack strength of the game cards constituting the deck of the attacking player with the total defense strength of the game cards constituting the deck of the defending player.

  The game includes a practice game, a tournament, and the like, and a predetermined amount of experience values can be acquired according to the scale, result, and content of the game (how many points have been won). The more you win in a big tournament, the more experience points you can acquire, and by accumulating experience points, the player's “case” goes up. In this embodiment, as the player's rank is higher, an advantageous effect such that the upper limit value of the parameter becomes higher can be obtained. In addition, the higher the rating, the higher the lottery probability when acquiring a game card. The method of determining the “case” is to be updated according to the amount of experience value acquired for a certain period (for example, one week in actual time) or to compare the experience value with other players. Determined by. Furthermore, the strength of the deck may be superior or inferior in accordance with the amount of experience points acquired even between teams of the same “case”.

  Also, by practicing in addition to the game, it is possible to raise the level of the game card and acquire experience values. In other words, the player who has logged in to the game and has practiced more games or practice is more likely to proceed with the game.

  In the baseball card game of this embodiment, the concept of time is provided in the game. For example, one week of actual time corresponds to one year of in-game time. Each game card is set with a parameter corresponding to the in-game time. A life parameter is set as an example of such a parameter. The life parameter decreases with the passage of time in the game, and when the predetermined time has elapsed and the life parameter becomes zero, the game card becomes unusable and is removed from the game card group owned by the player. That is, each game card can be used as a player only for a predetermined period.

  For example, if a baseball card game is supposed to be a club activity (baseball club) in a school, a championship in a big tournament will be given during the period (three years in the game) during which a certain player (for example, ace pitcher) is in school. aim. Then, after 3 years have passed in the game, the player graduates and is no longer on the team. That is, the life parameter of the game card becomes zero, and the game card is removed from the deck. Therefore, after the next fiscal year, it will be necessary to reorganize the deck (team) using another player (different game card) as a new ace pitcher.

  Note that the life parameter may not only change according to the passage of time in the game, but may change according to other factors.

<Data structure>
Next, the data structure showing the various information utilized in the game system 1 of this embodiment is demonstrated. The data storage unit 12 of the server device 10 includes card information relating to game cards as game media, possession card information representing cards owned by the player, deck information relating to decks organized by the player, player information representing player status, and the like. Are stored. In addition, lottery probability information defining the lottery probability for each attribute of the game card is stored.

  FIG. 4 is a diagram illustrating an example data structure of card information. FIG. 5 is a diagram showing an example of a data structure for cards owned by a player. FIG. 6 is a diagram showing an example of a data structure for a deck (game card group) organized by a player. FIG. 7 is a diagram illustrating a data structure example of player information during a game.

(Card information)
The card information includes a card ID as an example of identification information for identifying a game card, and various information regarding the game card associated with the card ID. For example, as shown in FIG. 4, the name of the character corresponding to the game card (player name), the attribute of the game card (position in the case of baseball), the maximum level, the attack power at the initial level, the defense power, the physical strength, etc. The various parameters (initial parameters) are included in the card information. Moreover, the lifetime parameter as described above is set for each game card. Furthermore, in addition to these pieces of information, information such as the rarity (rare value) of the game card and the skill (special ability) that is activated during the game may be provided. Normally, the higher the rarity of the game card, the higher the various parameters are set, and the higher the rarity card, the stronger the card.

(Owner card information)
The possessed card information is information representing a game card owned by the player (hereinafter also simply referred to as an owned card). Each game card has a unique parameter, and the parameter is stored in the data storage unit 12 in association with the ID of each game card. For example, as shown in FIG. 5, the possessed card ID, the level of the player corresponding to the game card, and various parameters such as attack power, defense power, and physical strength at that level are included. Various parameters such as attack power may be calculated from the initial parameters (see FIG. 4) of the game card recorded as card information and the current level of the game card. In addition, the possessed card information includes information about the time when the player acquired the game card, and the life parameter of each game card is changed based on the acquisition time information and the elapsed time in the game. May be. For example, as described above, when a baseball guard game is supposed to be a club activity, after obtaining a game card (after a player enters school), the life parameter will be Becomes zero (the player graduates). When the life parameter becomes zero, the game card corresponding to the player is removed from the possessed card information.

(Deck information)
The deck information is information representing a game card group for battle organized as a team from among the game cards owned by the player. When the player organizes the deck, as shown in FIG. 6, the player organizes the deck by setting a predetermined number of game cards for each attribute. In the baseball card game of the present embodiment, one game card (player) is set for each of the attributes of pitcher, maintenance, first base, second base, third base, and shortstop. Then, three game cards are set for the outfielder attributes. As a result, a team of nine players is formed. Based on the parameters set for these nine game cards, the total strength of the deck organized by the player is calculated. In other words, a team with a larger number of game cards (that is, better players) having higher parameters can advantageously advance a battle (such as a game).

  In addition to the game cards corresponding to nine players, a game card corresponding to a manager or manager in the deck may be set, or a game card having a special skill may be set.

(Player information)
The player information is information representing the state of the player in the game. For example, as shown in FIG. 7, it includes information such as the player's case, experience value, game play time, number of wins in the battle, etc. at a certain point in time. These pieces of information are referred to when calculating the degree of progress of the player in the game. The degree of progress will be described later.

(Lottery probability information)
The lottery probability information is information that defines the lottery probability of the game card when the player acquires the game card. The lottery probability information will be described later with reference to FIG. 9 and FIG.

=== Embodiment ===
<How to get game media>

  A method for the player to acquire a game medium (game card) will be described. A game card (game medium) used in the game of this embodiment is given to each player by the grant unit 114 of the server device 10. As a means for giving a game card, “lottery” is mainly used. The “lottery” in the present embodiment is executed in response to a request from the player, and a game card is extracted from a plurality of types of game cards based on a predetermined probability, and the extracted game card is given to the player. , Added to the player's own card information. The lottery of game cards is performed by the lottery unit 111 of the control unit 11.

  8A and 8B are diagrams for explaining the lottery probability of a game card when a lottery is performed. In the case of a baseball card game like this embodiment, seven types of attribute (position) game cards are set (see FIG. 6), and the probability that a card with each attribute is usually drawn is 14.3% (1 / 7). In other words, cards with all attributes are drawn evenly. For example, even when the player expects to acquire a game card having the pitcher attribute, the probability that the pitcher's game card can be acquired by lottery is 1/7 (FIG. 8A). Further, when the rarity is set for the game card, the lottery probability is changed for each rarity. Usually, the higher the rarity game card, the lower the lottery probability. Furthermore, in the present embodiment, the higher the player's rank, the higher the probability of drawing a game card with higher rarity. For example, in FIG. 8B, when there are eight cases from prestigious to super-weak, and when the player's case is the lowest, the draw probability of the SSSR game card with the highest rarity is only 0.6%. However, in the case of the prestigious player with the highest rank, the SSSR game card draw probability is 7.1%, making it easy to obtain a game card with high rarity. In other words, the player can easily obtain a game card with higher rarity by obtaining a lot of experience points and improving the rank.

<Regarding changes in lottery probability>
In this embodiment, when a lottery is performed, the higher the rating, the easier it is to obtain a powerful card with higher rarity. On the other hand, it is difficult to obtain a game card with desired attributes, no matter how high the rating. This is because the lottery probabilities for each attribute are basically the same (see FIG. 8A), and the probability that a game card with a desired attribute can be acquired does not change. If the desired card is not easily obtained, the player may lose interest in the game. In particular, as in the baseball card game of this embodiment, when a player (game card) cannot be used over time due to the life parameter, it is necessary to replenish a new player (game card) in place of the player in the deck. However, if it is difficult to obtain a game card with a desired attribute, it will not be possible to replenish sufficiently, and the player may give up on continuing the game.

  Therefore, in the present embodiment, by changing the game card lottery probability for each attribute, it is easy to obtain a game card having an attribute desired by the player. Further, in order to prompt the player to continuously log in, the game card lottery probability is changed in accordance with the degree of game progress of the player.

  FIG. 9 is a diagram for explaining the lottery probability of the game card of each attribute in the present embodiment. The lottery probability variation processing unit 113 varies the lottery probability of the game card according to each attribute. For example, a lottery probability of a game card with a certain attribute is set higher than a lottery probability of a game card with another attribute. In FIG. 9, the lottery probability is changed so that the lottery probability of the game card having the pitcher attribute is higher than the lottery probability of the game card having the other attribute. When the lottery probability of a game card with a certain attribute is changed, a screen (not shown) informing the player of that fact (in the case of FIG. 9, the lottery probability of a game card with a pitcher attribute has increased) Is generated by the screen generation unit 115 and displayed on the terminal display unit 24 of the player terminal 20. The player looks at the display and executes the lottery when the lottery probability of the game card having the desired attribute is changed to be high, so that it becomes easy to acquire the game card having the desired attribute.

  Furthermore, in this embodiment, even with game cards having the same attributes, the lottery probability is changed based on the progress of the game of the player. The progress of the game is determined based on predetermined parameters during the game. The progress processing unit 112 of the control unit 11 calculates the degree of progress of the game by the player based on a predetermined parameter while proceeding with the game. As this predetermined parameter, for example, the number of times a player has played a practice game during a certain period, the game play time of the player, and the like are referred to, and the degree of progress of the game is calculated based on the parameter. The period for calculating the degree of progress can be one day in real time or several hours from morning to night.

  In FIG. 9, the degree of progress is represented as a class. The lottery probability change processing unit 113 changes the lottery probability so that the higher the player class is, that is, the higher the degree of progress calculated at a certain time is, the higher the lottery probability of a game card with a specific attribute is. For example, when the lottery probability of a game card with a pitcher attribute is made higher than the lottery probability of a game card with another attribute, the lottery probability is changed to be higher than the game card with another attribute as the player class is higher. . In the example of FIG. 9, when the player class is the lowest C, the lottery probability of the game cards other than the pitcher is 13.9%, whereas the lottery probability of the game card of the pitcher is 16.6%. The fluctuation range is small. On the other hand, when the player's class is the highest S, the lottery probability of the game cards other than the pitcher is 9.1%, whereas the lottery probability of the pitcher's game card is 45.4%. The probability is very high.

  In addition, the lottery probability is actually changed after a predetermined period from a certain time when the progress degree is calculated. For example, the lottery probability of the game card at the time of tomorrow is changed based on the degree of progress calculated at the current time.

  This makes it easier for the player to acquire a game card having a desired attribute. For example, when a game card with a pitcher attribute is desired, the progress of the game is increased by performing a lot of practice games, etc., and the lottery probability of the game card with a pitcher attribute is highly varied after a predetermined time has elapsed. By executing the lottery, it becomes easy to obtain a game card having the pitcher attribute. At that time, information on when and how much the lottery probability of which attribute game card is changed may be displayed in advance on the game screen. By confirming information on the fluctuation of the lottery probability on the screen, the player can grasp at what timing the progress of the game should be increased. Further, by displaying the game progress degree (class in the example of FIG. 9) for each player on the game screen (for example, my page screen), it becomes easy to grasp the lottery probability applied to the player.

  With such a method, the player logs into the game and increases the degree of progress of the game, and as a result, it becomes easy to understand that the lottery probability of a game card having a predetermined attribute varies highly. And it becomes easy to acquire a desired game card by logging in to a game again and performing a lottery at the timing when the lottery probability of the game card of the attribute which wants to acquire actually fluctuates highly. This makes it possible to prompt the player to log in continuously.

<Regarding the periodic fluctuation of the lottery probability>
In this embodiment, the variation of the lottery probability of the game card may be set periodically. That is, the lottery probability of each attribute game card (each position such as a pitcher, catcher, outfielder, etc.) may be set to change every predetermined period.

  FIG. 10 is a diagram for explaining a case where the lottery probability of the game cards having the respective attributes periodically varies. In the case of FIG. 10, the game cards having seven attributes (positions) are set so that the lottery probability varies with a cycle of one week. Specifically, first, the pitcher's attribute lottery probability increases on Monday. On Tuesday, the catcher attribute lottery probability is high, and on Wednesday, the first baseman attribute lottery probability is high. Then, on Monday one week later, the lottery probability of the pitcher attribute is increased again. That is, the lottery probability of a game card having a predetermined attribute varies every week. At this time, the lottery probability variation processing unit 113 sets a cycle for varying the lottery probability of the game card for each attribute. Thus, by periodically changing the lottery probability of the game medium for each attribute, it becomes easier to understand at which timing the lottery probability of the game card of which attribute changes.

  As described above, in the baseball card game of the present embodiment, the degree of progress of the game by the player is calculated, and the lottery probability varies according to the calculated degree of progress. This makes it easier for the player to acquire a game car having a desired attribute. For example, it is assumed that the player desires a game card having a pitcher attribute. Since the game card with the pitcher attribute is raised every Monday, the probability of the lottery is changed, so that the player performs a practice game on Sunday, which is the day before Monday, to increase the progress of the game. And by running a lottery on Monday, the next day, it becomes easier to get a game card with the pitcher's attribute than to run a lottery on other days, and get a card with higher rarity depending on the degree of progress It becomes easy. That is, the result of the player's efforts to advance the game on the previous day is reflected in the lottery probability on the next day. As a result, it is possible to prompt the player to log in the next day following the previous day.

  In FIG. 10, the lottery probability fluctuates in the same cycle (one week cycle) for each attribute game card, but the lottery probability fluctuation cycle may be different for each attribute. For example, the lottery probability of the game card with the pitcher attribute may be changed every other day, and the lottery probability of the game card with the catcher attribute may be changed every three days.

  In the present embodiment, the lottery probability variation processing unit 113 periodically sets an attribute that varies the lottery probability among the attributes of the game card. In the example of FIG. 10, the pitcher attribute game card is changed every Monday so that the lottery probability becomes high. Similarly, the catcher attribute is every Tuesday, the first baseman attribute is every Wednesday, the second baseman attribute is every Thursday, the third baser attribute every Friday, the shortstop attribute is every Saturday, and the outfielder attribute is Sunday. Every time, the lottery probability is changed so as to increase. By periodically setting an attribute that increases the lottery probability (in the case of FIG. 10, each attribute has a period of one week), it becomes easier for the player to acquire a game card having a desired attribute. For example, if a player wants to obtain a catcher and a gamer's game card, the card can be obtained by performing a lottery on a Tuesday when the catcher's lottery probability is high and on a Saturday when the player's lottery probability is high. Increases nature. To that end, a game with a desired attribute can be obtained by increasing the progress of the game, such as actively logging in to the game on Monday, which is the day before Tuesday, and Friday, the day before Saturday, and performing many practice games. The card lottery probability can be further increased.

  In particular, in the baseball card game of this embodiment, since a life parameter is set for the game card, a great effect can be expected. For example, if a baseball card game is assumed to be a baseball club, no matter how strong an ace-class player (ie, a game card with high parameters) graduates from the deck after 3 years of in-game time has passed. It will be removed. In that case, it is necessary to replenish a new player (game card) to the position (attribute) in which the ace-class player has lost, but if the attribute that increases the lottery probability is set periodically, it is lost A player (game card) of a position (attribute) can be obtained efficiently. In addition, when it is desired to enhance the strength of the deck, the chance of acquiring a game card for each position (attribute) increases, so that the strength can be efficiently reinforced.

  Furthermore, log in to the game the previous day to increase the degree of progress, and notify the player who has logged in again to perform the lottery on the next day that the game card with other attributes will have a higher probability of drawing on the next day. Thus, it is possible to encourage the player to try to log in to the game for another day, and to promote playing the game continuously.

<Flow when adding game media>
Here, a specific operation when giving a game medium (game card) will be briefly described. FIG. 11 is a flowchart for explaining the operation at the time of giving a game content.

  First, a player who desires to acquire a game card uses the player terminal 20 to make a game media grant request (that is, a request for executing a lottery) (S001). The request is transmitted via the network 2 and accepted by the server device 10 (S002). When a request for lottery execution is accepted, a lottery probability is determined (S003). The control unit 11 of the server device 10 accesses the player information and the lottery probability information stored in the data storage unit 12 and reads information necessary for determining the lottery probability. Specifically, lottery probability information based on the current case of the player, the degree of progress of the game calculated by the progress processing unit 112, and the lottery probability changed by the lottery probability fluctuation processing unit 113 is read. Based on the information, the lottery probability of the player is determined. After the lottery probability is determined, the lottery unit 111 actually draws game cards (S004).

  Thereafter, a process of giving the selected game card to the player is performed (S005). The granting unit 114 stores the lottery game card in addition to the player's possessed card information. As a result, the player has acquired a new game card.

  When the lottery is performed, the screen generation unit 115 generates screen data for notifying the player of the result of the lottery (S006). FIG. 12 is a diagram illustrating an example of the result notification screen. On the result notification screen, information about the game card acquired by the player by lottery is displayed. For example, attributes (positions), rarity, initial parameters, etc. are displayed as information on the game card. Further, points consumed for executing the lottery (lottery points), the amount charged, and the number of game cards currently owned by the player may be displayed. The generated result notification screen data is transmitted to the player terminal 20 and displayed on the terminal display unit 24 (S007). The player can check the newly acquired game card by looking at the screen.

  Thus, in this embodiment, it is possible to promote the player to continuously play the game while increasing the interest of the player by changing the lottery probability of the game card.

=== Other Embodiments ===
The above-described embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof. The embodiments described below are also included in the present invention.

<About the baseball card game>
In the embodiment described above, the baseball card game has been described as an example of a game that can prompt the player to continuously log in. However, the type of game is not limited to this, and the present invention is also implemented for other games. The form is applicable. For example, it may be a race game in which a car race with an opponent is performed. In this case, the game medium (game card) is not a player but an automobile part, and an attribute corresponding to the type of the part is set. It is assumed that the parts are consumed as the life parameter decreases. In such a game, it is possible to prompt the player to continuously log in by changing the lottery probability of the game media used in the game.

<About life parameter>
In the above-described embodiment, the “lifetime parameter” that increases / decreases with the elapse of the in-game time is described as the parameter set for the game card (game medium). However, the life parameter is based on other than the elapse of the in-game time. It may change. For example, an event such as “study abroad” or “vacation” may occur in the game, and when the event occurs, the decrease in the life parameter may be stopped or recovered. Conversely, the life parameter may be shortened by the occurrence of an event such as “injury”.

  In a racing game, the life parameter of a part may be restored by performing “maintenance”, or the life parameter of the part may be shortened by “crashing” during a race.

<Information processing device>
In the above-described embodiment, the game system 1 including one server device 10 is described as an example of the information processing device. However, the present invention is not limited thereto, and a plurality of server devices 10 are provided as information processing devices. The game system 1 may be used. That is, a plurality of server devices 10 may be connected via the network 2 and each server device 10 may perform various processes in a distributed manner.

  Moreover, it is good also as a structure which the player terminal 20 bears a part of function as an information processing apparatus. In this case, the server device 10 and the player terminal 20 constitute an information processing device.

<Game program>
In the game system 1 in the above-described embodiment, an example has been described in which the server device 10 and the player terminal 20 cooperate to change the lottery probability of the game media used in the game and prompt the player to continuously log in. However, the present invention includes a game program for executing these processes. That is, the server device 10 or the player terminal 20 as the information processing device may execute the above-described processes based on the game program.
